I can't seem to find any information on the subject to confirm my theory, But I have a series of movie-length files (BRDs down-scaled to 720p23.98) that import and open just fine in Premire CS3, but refuse to work correctly in AE CS3. Upon import I get the following error:

This error continues to constantly pop up every time the footage needs to be rendered on the timeline... that is, until I right-click and choose Interpret Footage -> Main and Conform to frame rate X. X can be anything I want to give it, the correct frame rate, an incorrect one, whatever... i've tried 24, 23.98, 23.976... they all result in the file now working correctly in AE and the error going away. The catch, however, is that the file is only recognized as being around 22 minutes long, not the 90 to 100 minutes it should be (it's doing this for all 4 of the movies i'm using).

Is there a way to fix this? Or have I found a limitation in AE for the size of a single imported video?

----------------------------------

EDIT - I just used AD's new avisynth plugin and assumefps(23.978)'d the problem away.

I'm basically doing that with avisynth scripts. As i've said twice now, there is no longer any problem.

That's not how Premiere and AE are supposed to work though. You're supposed to be able to import your premiere projects in AE and add in your effect work without having to do more than one, final, export.

I still have a trauma of this method. I tried it with v4.1. It sucked ass. It was way too unstable with all those strange processes in the background. I take this extra time and harddisc space for the sake of spareing me a lot of trouble and frustration.
